383 headers fit 440?

[fwi]

They fit my 1965 B body 1969 stock heads, will they fit stock 440 heads?

Yes stock heads are the same dimensions

TTI makes different part numbers for B vs RB.

Most others do not.

There is about an inch difference in height between the two blocks, and the angle of the tubes can come into play as well.

Could be an issue or not at all, or just cause the need for minor mods or collector pipe routing.

The difference between the RB & B blocks is about .75" in deck height. I'd imagine TTI offers a slightly shorter set for better ground clearance while others say deal with it but that's just guessing.

While what you note is true, the OP question refers to the heads only. The body style and transmission type is a separate issue.

I just went through this trying to buy fenderwell headers through Dougs. The headers will fit to the heads but it's the fitting in the car with the block angle/height that changes things.
